CAN: Network for Thousands of Applications Outside Automotive
Design How-To  
6/26/2003   Post a comment
First defined by the European automotive electronics company Robert Bosch GmbH as an internal project to develop an in-vehicle network in 1983, the controller-area network (CAN) is still commonly associated with the worldwide automotive industry. But it's hard to keep a robust, simple, and versatile network protocol confined to a single market segment. Jack Shandle describes the standard and its applications outside of the automotive industry.
Reverse Media Independent Interface (RevMII) Block Architecture
Design How-To  
6/18/2003   1 comment
This article describes a design of a simple digital device able to connect two Ethernet MACs with configurable point-to-point link (Reverse MII Interface block). This link is proposed to be a simple and low-cost alternative to using Ethernet PHY in the system. The block might be used either inside an ASIC or on the system board (FPGA). The device described emulates two Ethernet PHY-level blocks connected together and is completely transparent to Ethernet MACs.

Cost-cutting measures taken in 2002 to buttress semiconductor companies' sliding profits became evident in the year's rankings, as players exited flagging or noncore product lines, or combined efforts to share research and development and manufacturing resources.
A Summary of Short-Range Wireless in 2003
Design How-To  
6/16/2003   Post a comment
Ten years ago, the founders of the Infrared Data Association (IrDA) asked themselves a simple question: what's the best way to link two devices without a cable? This simple idea has now blossomed into several industries offering a bewildering assortment of products and protocols. In this article, Glade Diviney explores the world of wireless communications mechanisms. The three most popular standards for short-range wireless data communication are IrDA, Bluetooth, and Wi-Fi.

Power Management Chip Vendors Zero in on Wireless
News & Analysis  
6/3/2003   Post a comment
Power-managing ICs in wireless products are now playing a major role in system-level solutions. Cell phones, which are being combined with PDAs and cameras, are becoming increasingly small, dense and power-hungry, offsetting the size and energy density advances made by the lithium-ion battery sources powering them.

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
